[Pansy-Mae]

I actually had no idea what you were talking about so I took your reddit link ( never heard of reddit before) and had a look. To be perfectly honest, at this stage of your development I don't think you would have a cat in hells chance of fooling anyone in that collection of extremely curvy ladies. No bra or insert could ever make you, or anyone else on here, look like them, much as we all wish we could.
Sorry, but you asked for honest thoughts.
Now, having said all that, the third one of your pictures does seem to show the start of some breast development, probably about average for 6 months, so I'd just carry on and enjoy the journey, if I were you.
